ELECTRIC SANITARY CLOSET.

SPECIFICATION forming part of Letters Patent No. 749,769, dated January19, 1904.

Application filed October 23, 1902.

To all whom it may concern.-

Be it known that I, JAMES H. VVILsoN, a citizen of the United States,residing in Lowell, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a cer tain new and useful Improvement inElectric Sanitary Closets, of which the following is a specification.

This invention relates to electric sanitary closets or privies arrangedto discharge upon an electric burner whereby the discharges areconsumed.

The closet herein described includes a shaft or chimney for the removalof odors, means for creating a current or draft of air through saidchimney while a seat or platform is depressed by the weight of a personthereon, means for the convenient cleaning of the burner, and means forthe reception and removal of the ashes; and it consists in thecombinations hereinafter described and claimed.

In the accompanying drawings on two sheets, Figure l is a side elevationof an electric sanitary closet provided with my improvement and asuitable chimney or air-shaft; Fig. 2, an enlarged vertical section onthe line 2 2 in Fig. 3 of the part of the chimney or airshaft whichcontains the air-heater and of said heater; Fig. 3, a section of thechimney and heater on the line 3 3 in Fig. 2; Fig. 4, a vertical sectionof the closet and apart of the chimney on the line 4 t in Fig. 5; Fig.5, a front elevation of the closet; Fig. 6, a top plan of the closet,the chimney being in horizontal section; Fig. 7, a horizontal section ofthe closet and burner on the line 7 7 in Fig. 4;.

The drawings represent the closet as it might be used in a car, house,or other structure.

A indicates the floor, and B the roof or ceiling, of a car or buildingof any usual construction.

C indicates the bowl or upper part of the closet, said bowl having nearthe bottom an external flange 0, which rests upon the floor, the lowerend 0 of the bowl projecting down through the floor, as shown in Fig.4:. The back of the bowl C is connected to a chimney or air-shaft D,which passes up through the roof B and is provided at its upper end.with a suitable ventilator or hood (Z, adapted nor- Serial No. 128,438.(No model.)

mally to draw a current of air from the bowl C, to which air is admittedthrough the seat (1 and between said seat and the top of said bowl andalso through air holes or slots 0 with which said bowl is preferablyprovided below said seat to admit air to said bowl when said seat isoccupied.

The seat C is of usual form and is hinged at the back at c and near itsfront rests upon a vertical rod F, the lower end of which is pivoted toa bracketf, secured to the free rear end of a platform G, hinged at itsfront end at g to the floor A.

The platform G will be depressed to the level of the floor A by theweight of a person standing thereon or sitting on the seat, thedepression of said seat acting on the platform through the rod F; butthe rear end of said platform is normally raised above said floorlevelby a lever g, secured thereto and carrying a weight heavy enough to liftsaid seat and platform. The upward movement of the platform is limitedin any convenient manner, as by the bracket f coming in contact with theunder side of the floor A.

The seat may be raised by hand when desired, not being attached to therod F, but merely resting on the top of said rod.

The raising of the lever g by the depression of the seat C or platform Gserves to close an electric circuit H by means of a circuit-closer I, asa lmife-switch, the blade '5 of which is carried by said lever againstor between sheet-metal springs 2 secured to the under side of the floorA.

Current is supplied to the circuit from any convenient source, as fromthe trolley-line, if the closet be contained in an electric car. I haveindicated a dynamo I in Fig. '1 as a source of current-supply.

In the circuit H are arranged in series with the dynamo a heater E andan electric burner J both of which are hereinafter described.

The lower part of receptacle C of the closet receives the lower end ofthe bowl C and is secured in place by any usual or convenient means, asby bolts 0 which pass up through external ears or flanges 0 with whichthe upper end of the receptacle C is provided, into the floor A.

The chimney D is preferably provided with an enlargement or chamber (Zto contain draftcreating means, as an electric heater E, Figs. 2 and 3,which may be of any usual construction, except that the same ispreferably a plate V-shaped in cross-section, as shown, to get a greaterheating-surface without unduly enlarging the chamber (Z and to opposeless resistance to the air-current, the heater being represented asrectangular in plan and the lower part (Z of said chamber beingrepresented as shaped like a hopper.

The heater E is a resistance-circuit 0, arranged in a frame 6 ofnon-conducting material, as earthenware or porcelain, said frame beingprovided with ears 0 which pass out through the sides of the chamber cland which contain the terminals of the circuit 6 and insulate them fromthe chimney, said ears 0 supporting one end of the heater, while theother end thereof rests upon a horizontal bar 6 of non-combustibleinsulatingmaterial,(secured in said chamber d',) or is otherwise insulated from said chimney.

An electric burner J, which may be substantially like the heater E orlike any electric heater of ordinary construction, except that it isV-shaped in longitudinal section, is pivoted at one end in thereceptacle C below the bowl C and forms the pan or bottom of said bowl,the terminals j j of said burner J passing through insulating sleeves,which form the ears j of said burner, and turn in holes in the sides ofsaid receptacle.

The burner J is preferably provided with slots 7' to allow liquidmatters and ashes to pass therethrough into a suitable drawer c.

To one of the ears 7" of the burner J outside of the receptacle C isrigidly secured a lever 7' normally engaged by a catch, Figs. 1 and 5,to retain the burner in the operative position. (Shown by full lines inFig. L.) By releasing said catch the lever may be turned to throw saidburner into the position shown by dotted lines in Fig. 4 to empty anymatters too large to pass through the slots 7" into said drawer 0. Thedrawer may be removed, emptied, and replaced.

It is obvious that a person stepping on the platform will close thecircuit, and thereby cause an increase of temperature in the heater Eand an increased current of air to pass up the chimney from the closetand will also cause the burner to be heated, and these temperatures willbe maintained while the seat or the platform is occupied. In this mannerall offensive odors will be carried up the chimney and matters depositedon the burner will be consumed.

Obviously the seat, platform, and any parts with which the user mightcome in contact should be of insulating material or insulated from thecircuit.

I claim as my invention 1. The combination in a sanitary closet of abowl, a part adapted to be depressed by the weight of a person thereon,an electric circuit, means for closing said circuit by the depression ofsaid part, and a burner arranged in said circuit and forming the pan orbottom of said bowl.

2. The combination in a sanitary closet of a bowl, a seat adapted to bedepressed, an electric circuit, means for closing said circuit by thedepression of said seat, and a burner arranged in said circuit belowsaid seat and forming the pan or bottom of said bowl.

3. The combination in a sanitary closet of a bowl, a seat, a platformadapted to be depressed by the weight of a person approaching or leavingsaid closet, an electric circuit, means for closing said circuit by thedepres sion of said platform, and a burner arranged in said circuitbelow said seat and forming the pan or bottom of said bowl.

4. The combination in a sanitary closet of a bowl, a seat, an electriccircuit, means for closing said circuit by the weight of a person usingsaid closet, a burner arranged in said circuit and forming the pan ofsaid closet, a suitable receptacle in which said burner is pivoted,means of discharging the contents of said burner andv a removable drawerarranged to slide in said receptacle below said burner and to receivematters discharged from said burner.

The combination of a sanitary closet, a chimney connected therewith, anormally open electric circuit, a burner arranged in said circuit withinsaid closet, a heater situated in said chimney and included in saidcircuit, said burner and heater being operated by the closing of saidcircuit, and means of closing said circuit.

In witness whereof I have aflixed my signature in presence of twowitnesses.

JAMES H. W'ILSON.
